Hi all, Having a problem with a query that's returning 486,057 results when it most definitely should NOT be doing that.
I have two tables: 1 for a list of customers that purchase product A, another for customers who purchased product B. Columns are: Id First Last Email I am trying to compare table 1 to table 2 to get a result set that gives me the contact info (table columns) for those whose email addresses in table 1 DON'T EQUAL those in table two. In table one I have 2026 records In table two I have 240 records The query is this: SELECT * FROM producta_customers AS t1, productb_customers AS t2 WHERE t1.email != t2.email When I do this query. I get 486,057 results returne. Where am I going wrong? Any ideas? Thanks so much for the help!
